Guidelines for solving Exercise 2 Page 50 Math 5 Textbook Practice

Problem:
Perform addition then use the commutative property to retest:
a) 9.46 + 3.8;
b) 45.08 + 24.97;
c) 0.07 + 0.09.

Solution Method:
- First, perform addition of two decimal numbers as usual, you can draft the calculation and then fill in the given expression.
- Then, swap the two terms and perform addition to compare the results.
- If the result of the calculation a + b matches the result of the calculation b + a => Perform the calculation correctly
- Otherwise, if the results do not match, redo the addition.

Answer:
a) 9.46 + 3.8 = 13.26 try again 3.8 + 9.46 = 13.26
b) 45.08 + 24.97 = 70.05 try again 24.97 + 45.08 = 70.05
c) 0.07 + 0.09 = 0.16 try again 0.09 + 0.07 = 0.16.

Frequently Asked Questions

How do you apply the commutative property in addition of decimal numbers?

To apply the commutative property in decimal addition, perform the addition in both orders, a + b and b + a. If both results match, it confirms the property holds true.

What is the solution method for Exercise 2 on page 50?

The solution method for Exercise 2 involves first adding the decimal numbers as usual, then swapping the terms and adding again to compare the results for accuracy.

Can you provide an example of using the commutative property with decimal addition?

Certainly! For example, when adding 9.46 and 3.8, both 9.46 + 3.8 and 3.8 + 9.46 yield the same result, 13.26, demonstrating the commutative property effectively.

What results should be expected when solving Exercise 2 from the Math 5 textbook?

When solving Exercise 2, expect the results for all additions to match when performed in either order. For example, 45.08 + 24.97 equals 70.05, just like 24.97 + 45.08.
